I applied via Walk-in and was interviewed before Jul 2022. There were 3 interview rounds.
Blue screen of death is a Windows operating system error screen that appears when a system error occurs.
Occurs when a critical system error is detected by Windows
Causes the computer to stop functioning and display a blue screen with error message
Commonly known as BSOD
Can be caused by hardware or software issues
BIOS stands for Basic Input/Output System. It is a firmware used to perform hardware initialization during the booting process.
BIOS is a firmware embedded on a small chip on the motherboard.
It is responsible for initializing and testing hardware components during the boot process.
BIOS provides the basic instructions for the computer to operate before the operating system takes over.
It also manages the communication bet...

RAM is volatile memory used for temporary storage while ROM is non-volatile memory used for permanent storage.
RAM stands for Random Access Memory and is used for temporary storage of data and program instructions.
ROM stands for Read-Only Memory and is used for permanent storage of firmware and software that rarely changes.
RAM is volatile, meaning it loses its data when power is turned off, while ROM is non-volatile and
Mainframe computer is a large, powerful, and high-performance computer used by organizations for critical applications and large-scale data processing.
Mainframes are designed to handle massive amounts of data and transactions.
They are known for their reliability, security, and scalability.
Examples of mainframe manufacturers include IBM, Unisys, and Fujitsu.
Networking is the practice of connecting computers and other devices to share resources and information.
Networking involves connecting devices such as computers, printers, and servers to share resources like files and printers.
Types of networking include LAN (Local Area Network), WAN (Wide Area Network), WLAN (Wireless Local Area Network), and MAN (Metropolitan Area Network).
LANs are used in small areas like homes or o...

Use Dijkstra's algorithm to find the shortest path between 2 vertices in a graph.
Implement Dijkstra's algorithm to find the shortest path
Create a priority queue to keep track of the vertices with the shortest distance
Use a visited set to avoid revisiting vertices
Stop when the destination vertex is reached
Return the shortest path found
Example: finding the shortest path between A and D in a graph with weighted edges: A->...
Find pairs in an array with sum equal to 0.
Use a hash table to store the frequency of each element.
Iterate through the array and for each element, check if its complement (negative value) exists in the hash table.
If it exists, add the frequency of the complement to the count of pairs.
Return the count of pairs.
Example: array = [2, -2, 3, 0, -3], pairs = 2 (-2, 2 and -3, 3)
I appeared for an interview in Jul 2019.
Design a traffic signal system
Identify the number of lanes and intersections
Determine the traffic flow and peak hours
Choose appropriate sensors and controllers
Implement a synchronization algorithm
Consider emergency vehicle prioritization
Include pedestrian crossing signals
Ensure compliance with local regulations
Hashmap is a data structure that stores key-value pairs and provides constant time complexity for insertion, deletion, and retrieval.
Hashmap uses hashing function to map keys to indices in an array
Collisions can occur when multiple keys map to the same index, which can be resolved using separate chaining or open addressing
Java implementation: HashMap
Printing patterns using code
Identify the pattern to be printed
Use loops to print the pattern
Adjust the loop variables to control the pattern
Use conditional statements to modify the pattern
Examples: printing stars, triangles, squares, etc.
Common point in linked list refers to the node where two or more linked lists intersect.
The common point can be found by traversing both linked lists and comparing the nodes.
The common point can also be found by using two pointers, one for each linked list, and moving them until they meet at the common point.
Examples include finding the intersection point of two linked lists or finding the loop in a linked list.

Learning programming languages is important for software engineers to effectively communicate with computers and develop software solutions.
Programming languages are the foundation of software development.
Learning multiple languages expands the range of problems a software engineer can solve.
Different languages have different strengths and are suited for different tasks.
Knowing multiple languages improves adaptability ...
